2About us

Claudius Peters Projects GmbH, Germany and Claudius

Peters Technologies SAS, France are part of the

Technologies Division of Claudius Peters Group GmbH,

headquartered in Buxtehude, near Hamburg, offering

technologies in the field of materials handling and

processing and providing turnkey or semi-turnkey systems

to a wide range of industries. Claudius Peters Group GmbH

is a wholly owned subsidiary of Langley Holdings plc, a

privately controlled UK engineering group, with regional

offices in the Americas, Europe, China and the Far East.

Claudius Peters is one of the worlds leading suppliers of

pneumatic conveying systems. Our experience includes the

handling of more than 13,000 different bulk solids, which we

have analyzed to determine the appropriate conveying

procedure. Claudius Peters can deliver the complete plant

including examination of the bulk solids, selection of the

conveying system and the surrounding auxiliary

components. Erection and commissioning of all systems

are provided by Claudius Peters.

It all starts with the material to be conveyed...

Claudius Peters can either analyze a material sample or

work to the clients specification to design the necessary

pneumatic equipment, including the bulk solid feeder, the air

supply equipment, the conveying pipeline and the air/solid

classifier. The flow diagram below shows our working

procedure which is certified according to DIN EN ISO 9001.

Claudius Peters

The Claudius Peters Technikum (Technical Center) offers

clients the advantages of a laboratory for bulk solids and a

test facility equipped with all types of conveying systems.

Conveying lines up to 800m long with different pipe

diameters are available. Our laboratory gives us the

capability to design and supply systems which are optimally

calculated with regards to process, cost and operating

parameters.

In the Claudius Peters Technikum, different conveying

procedures can be tested with any operating condition with

regards to loads, gas velocities, conveying pressures and

conveying distances. The wide range of tests, backed up by

years of experience, allow us to design reliable conveying

systems with minimal power consumption.

An experienced partner in conveying technology

Each material examined in our laboratory is documented in

a test report. The materials are measured for deaeration

time, density, humidity, wall friction angle, etc. The data is

supported by EDP and is used for the optimum design of

the plant.

4The product characteristics analyzed from the bulk

material samples are used for the configuration of

the plant. The plant typically consists of a bulk

solids feeder, pressure generator, conveying pipe

and a separator. For example, we classify the bulk

solids according to the Geldart diagram. The

materials which can easily be conveyed in a dense

phase mode are located in the yellow areas. The

results of the bulk solids test, the conveying tests

and the basic conveyance data from the customer

ensure that the appropriate conveying procedure is

selected. Once the most suitable procedure has

been determined, the plant can be optimally

designed at an efficient and acceptable

consumption of power. Depending on the required task and

the bulk solids behaviour, one of the Claudius Peters

conveying modes is selected with our bulk solids feeders.

Determination of the conveying process

Five proven conveying modes for bulk solids

Claudius Peters conveying systems range from FLOWCON,

the conventional flow conveyance for feeding coal burners,

to BYCON, a bypass conveyance with exterior additional air

injection for reduced wear and minimal energy

consumption.

Types of Feeder for plant configuration

The variety of possible feeders with their standardized rangeof applications is indicated in the chart below. Other solutionsfor the ranges not included in the chart, can also be supplied.

Claudius Peters delivers positive pressure and suction

conveying systems. The illustration shows the principle

structure of a positive pressure vessel conveying system.

This system introduces defined quantities of bulk solids into

the conveyor pipe against the conveying pressure without

air leakage losses. Claudius Peters offers the complete

range of suitable feeder types.

6For a better understanding of the concept:

What are the main features characterizing pressure vessel

conveying? What transport applications should require this

type of conveying system?

High availability Low maintenance requirements Partial load operation Suitable for dense phase conveyance Appropriate for all types of bulk solids Available sizes up to 50m3. Conveying distances up to 3500m Conveying pressures up to 30bar Systems with top or bottom discharge

The principle of the pressure vessel conveyanceat a glance:

In addition to conveying vessels, Claudius Peters also offers

injection vessels. These vessels are designed for injecting

substances against high counter pressures. The injection

vessels can be provided with distribution devices within the

conveying pipe to divide the material flow accordingly such

as feeding coal into a blast funace at various points.

8Conveyance with the Claudius Peters X-Pump is one of the

most successful systems developed by Claudius Peters. As

one of the core components of our product range, the

Claudius Peters X-Pump has been operating reliably for

clients all over the world for many years

Continuous conveyance Suitable for dense phase conveyance High availability Low maintenance Partial load operation possible Fine particle bulk solids possible Conveying volumes to 640m3

Conveying distances to 1500m Low construction height Pressure and shock resistant design Pulsation free conveyance

Conveyance with the Claudius Peters X-Pump

The bulk solids are fed into the pump surge bin to

be deaerated The pump surge bin is not an intermediate bin The rotating screw compresses the bulk solids to a

plug at the end of the screw. The screw is

completely filled with the solids The solids in the plug and the screw seal off the

conveying pressure The bulk solids pressure builds up and forces open

the check flap The solids are fed into the conveying air stream and

conveyance begins

Type 2 - Claudius Peters X-Pump

The Claudius Peters X-Pump is the optimum solids feeder

for a wide range of applications, including silos, preheaters

and pre-calciners, ship loaders and many more. The

Claudius Peters X-Pump capability is outstanding.

For example, 400t/h cement can be conveyed distances

of up to 1500m. Additionally, the geometry of the screw

is adjusted to accommodate the specific bulk solids

requirements.

Versatile and flexible

Special features: Variable arrangement of the pump outlet Different screw geometries and end flights End flights can be replaced separately Easy assembly, wear parts can be replaced with

minimal dismantling Screw supported at both ends of the shaft Individual screw geometry for each bulk solid Check flap with integrated damper Pulsation free conveyance

Examples for applications: Feeding of silo Injection of pulverized coal Transport of filter dust Feeding of preheater Ship loading and unloading

Capacity ranges: Conveying capacities to 400t/h cement equivalent

to 640m3/h Conveying pressures to 3.0bar gauge Conveying distances to 1500m Loads to 100kg solids per kg conveying gas

10

The Claudius Peters Airlift, a pneumatic lift, can vertically

convey solids to a maximum capacity of 900t/h. The Airlifts

other features include:

High availability Low investment costs Continuous operation Easy partial load operation All fluid bulk solids Conveyance with loads to 40kg solids per

kg of conveying gas Conveying heights to 120m Capacities to 900t/h Low power consumption

The principle of the Airlift is rapid transport of large quantities

of material with air

The bulk solids are continuously fed into the Airlift

pot The conveying air is fed to the conveyor pipe via a

nozzle Due to the aeration at the bottom of the airlift pot,

the bulk solids are partly fluidized prior to transport The solids column seals off the overpressure of the

conveying air The pressure of the solids column feeds the

fluidized solids into the conveyor pipe where it is

transported by the conveying gas

Type 3 - Claudius Peters Airlift

11

The Claudius Peters Airlift transports material vertically to

cyclone preheaters or storage silos. With throughputs to

900t/h, the Airlift is an efficient high capacity conveying

method. The Claudius Peters Airlift has a specialized

design called dosification (DOSCON) that has a variety of

applications.

Examples for applications

Feeding of heat exchangers Standby system for mechanical preheater feeding

such as bucket elevators Silo feeding Pulsation free, precise dosing (system: DOSCON) All types of vertical transports

Performance range

Throughputs of 10 to 900t/h Conveying heights up to 120m Bottom aeration Bottom cone for coarse bulk solids Several feed points using two-way gates in the

conveyor pipe Bulk solids and conveying gas can be separated by

the Claudius Peters expansion vessel

Bulk solids with difficult flow behaviours can be handled with

our feeding and conveyance unit. The Claudius Peters Blow

Feeder offers interesting features for all conveying

procedures requiring more than only throughput and

conveying distance specification.

High availability Compact design Partial load operation if required Closed, dust free system Pulsation free Throughputs to 100m3/h Continuous conveyance Conveying distances to 250m Fine grained and coarse grained bulk solids, low

abrasivity

The feeding roller, blow pan, and conveyor pipe are the

necessary equipment for the conveying process of the

blow feeder:

The bulk solid drops into a rotating feeding

chamber Through lateral air connections, the solid is blown

out of the lower chamber The bulk solid drops into the blow pan The conveying air picks up the bulk solid and

transports it within the conveyor pipe

Type 4 - Claudius Peters Blow Feeder

13

Not all types of applications demand high throughputs.

When average performance values are required at optimum

cost efficiency rates, Claudius Peters recommends a blow

feeder. This feeder has typical volume throughputs of 20-

30m3/h with a maximum of 100m3/h. Specifications

requiring this design are intermediate transports

applications and filter dust return.

Examples for applications

Silo feeding Intermediate transports Material return, i.e., bag discharge to the packer

prebin Filter dust return Average throughputs at optimum cost efficiency

rates

Capacity ranges

Throughputs to 100m3/h Conveying distances to 250m Conveying pressures to 0.4bar gauge or up to 1.0

bar gauge for only slightly abrasive bulk solids

14

The Claudius Peters Jet Feeder is the most compact of the

five feeder types available. This feeder offers important

advantages for the specific applications.

Continuous operation High operational safety Long life times Low investment costs High solids temperature capability Partial load operation without modification of the

conveying air flow Lean phase conveyance All bulk solids Closed dust free system Simple and space saving construction No movable parts in the solids flow Throughputs up to 6t/h Conveying pressures to 0.2bar gauge Loads to maximum of 6kg/kg

Type 5 - Claudius Peters Jet Feeder

Jet feeding is the conversion of static pressureinto kinetic energy

Bulk solids feeding directly from the prebin or

through a rotary feeder Within the nozzle, the static pressure of the

conveying gas is converted into kinetic energy The conveying gas draws the bulk solids into the

mixing chamber Within the connected diffuser, the kinetic energy of

the blended air and solids is reconverted into static

pressure

15

The Claudius Peters Jet Feeder is the best design for low

solid mass flows, adapting to different operating conditions.

The operating conditions determine the size and the type of

the nozzle. The variants with and without an aerated bottom

and the corresponding diameter of the transport pipeline,

provide a reliable conveying method.

Examples for applications

Silo feeding with minimized bulks solids flows Material return to a packing machine Filter dust return Economic operation with minimized bulk solids flows Conveyance of hot fly ash

The ideal feeder for low conveying capacities
